A former Hollyoaks actor has been found guilty of raping a 15-year-old girl at a house party after a jury rejected his claim he had 'sexsomnia.'

Simon Morris, 42, has yet to be sentenced for raping the teenager when he sneaked into her room at 6am after a birthday party.

The bit-part actor told the jury at Cardiff Crown Court he believed he had sexsomnia, where you engage in sexual activity while asleep, he said.

"I have a history of sleepwalking, checking my phone, gyrating against door frames and having sex with partners in my sleep. It’s quite embarrassing but I once engaged in sexual activity with a recent ex-girlfriend.

"I climbed on top of her in the middle of the night in a blank state. I have also had partial sex with my current partner and gyrated against her leg," he said, according to the Daily Mail.

The actor, who appeared in Hollyoaks in 2001 and in the 2000 film Shiner, even denied having sex with her until he was presented with DNA evidence.
